I don't know that people are saying she doesn't have a right to work, or that Columbia doesn't have a right to hire her.
But people can express displeasure with the University for giving her a paycheck.

Certainly have that right, but the editorialist in the first post does not seem to be much of a fan of the 1st Amendment if he wants to criticize Redford for planning to make a movie about the story and then having a prejudiced opinion of how that movie is going to end up.

Seems to me a good topic for a movie and until it is made you can't say that it is a biased presentation of the story.
